Make specified cells read-only to protect them from unwanted changes but still allow navigation and copying of data.

Overview

Disabling a cell makes the cell read-only or non-editable. Both have similar outcomes, with the following differences:

Read-only cell
readOnly: true
Non-editable cell
editor: false
Has an additional CSS class (htDimmed)Has no additional CSS class
Copy works, paste doesn’t workCopy-paste works
Drag-to-fill doesn’t workDrag-to-fill works
Can’t be changed by populateFromArray()Can be changed by populateFromArray()

Read-only grid

You can make the entire grid read-only by setting readOnly to true as a top-level grid option.

TypeScript
/* file: app.component.ts */
import { Component } from '@angular/core';
import { GridSettings } from '@handsontable/angular-wrapper';
@Component({
selector: 'example-readonly-grid',
standalone: false,
template: ` <div>
<hot-table [data]="data" [settings]="gridSettings"></hot-table>
</div>`,
})
export class ExampleReadonlyGridComponent {
readonly data = [
{ car: 'Tesla', year: 2017, chassis: 'black', bumper: 'black' },
{ car: 'Nissan', year: 2018, chassis: 'blue', bumper: 'blue' },
{ car: 'Chrysler', year: 2019, chassis: 'yellow', bumper: 'black' },
{ car: 'Volvo', year: 2020, chassis: 'white', bumper: 'gray' },
];
readonly gridSettings: GridSettings = {
readOnly: true,
height: 'auto',
colHeaders: ['Car', 'Year', 'Chassis color', 'Bumper color'],
autoWrapRow: true,
autoWrapCol: true
};
}

/* file: app.module.ts */

Read-only columns

In many use cases, you will need to configure a certain column to be read-only. This column will be available for keyboard navigation and copying data (Ctrl/Cmd+C). Editing and pasting data will be disabled.

To make a column read-only, declare it in the columns configuration option. You can also define a special renderer function that will dim the read-only values, providing a visual cue for the user that the cells are read-only.

Read-only specific cells

This example makes cells that contain the word “Nissan” read-only. It forces all cells to be processed by the cells function which will decide whether a cell’s metadata should have the readOnly property set.

TypeScript
/* file: app.component.ts */
import { AfterViewInit, Component, ViewChild } from '@angular/core';
import { GridSettings, HotTableComponent } from '@handsontable/angular-wrapper';
@Component({
selector: 'example2-disabled-cells',
standalone: false,
template: ` <div>
<hot-table [data]="data" [settings]="gridSettings"></hot-table>
</div>`,
})
export class Example2DisabledCellsComponent implements AfterViewInit {
@ViewChild(HotTableComponent, { static: false }) readonly hotTable!: HotTableComponent;
readonly data = [
{ car: 'Tesla', year: 2017, chassis: 'black', bumper: 'black' },
{ car: 'Nissan', year: 2018, chassis: 'blue', bumper: 'blue' },
{ car: 'Chrysler', year: 2019, chassis: 'yellow', bumper: 'black' },
{ car: 'Volvo', year: 2020, chassis: 'white', bumper: 'gray' },
];
readonly gridSettings: GridSettings ={
height: 'auto',
colHeaders: ['Car', 'Year', 'Chassis color', 'Bumper color'],
autoWrapRow: true,
autoWrapCol: true
};
ngAfterViewInit(): void {
const hot = this.hotTable?.hotInstance;
hot?.updateSettings({
cells: (row: number, col: number, _: any) => {
if (hot.getData()[row][col] === 'Nissan') {
return { readOnly: true };
}
return {};
},
});
}
}
/* end-file */
/* file: app.module.ts */
import { NgModule, ApplicationConfig } from '@angular/core';

registerAllModules();
export const appConfig: ApplicationConfig = {

}
],

@NgModule({

Non-editable cells behave like any other cells apart from preventing you from manually changing their values.

Non-editable columns

In many cases, you will need to configure a certain column to be non-editable. Doing this does not change its basic behaviour, apart from editing. This means that you can still use the keyboard navigation Ctrl/Cmd+C, and Ctrl/Cmd+V functionalities, and drag-to-fill, etc.

To make a column non-editable, declare it in the columns configuration option. You can also define a special renderer function that will dim the editor value. This will provide the user with a visual cue that the cell is non-editable.

TypeScript
/* file: app.component.ts */
import { Component } from '@angular/core';
import { GridSettings } from '@handsontable/angular-wrapper';
@Component({
selector: 'example3-disabled-cells',
standalone: false,
template: ` <div>
<hot-table [data]="data" [settings]="gridSettings"></hot-table>
</div>`,
})
export class Example3DisabledCellsComponent {
readonly data = [
{ car: 'Tesla', year: 2017, chassis: 'black', bumper: 'black' },
{ car: 'Nissan', year: 2018, chassis: 'blue', bumper: 'blue' },
{ car: 'Chrysler', year: 2019, chassis: 'yellow', bumper: 'black' },

readonly gridSettings: GridSettings = {

autoWrapRow: true,
autoWrapCol: true,

Non-editable specific cells

The following example shows the table with non-editable cells containing the word “Nissan”. This cell property is optional and you can easily set it in the Handsontable configuration.

TypeScript
/* file: app.component.ts */
import { AfterViewInit, Component, ViewChild } from '@angular/core';
import { GridSettings, HotTableComponent } from '@handsontable/angular-wrapper';
@Component({
selector: 'example4-disabled-cells',
standalone: false,
template: ` <div>
<hot-table [data]="data" [settings]="gridSettings"></hot-table>
</div>`,
})
export class Example4DisabledCellsComponent implements AfterViewInit {
@ViewChild(HotTableComponent, { static: false }) readonly hotTable!: HotTableComponent;
readonly data = [
{ car: 'Tesla', year: 2017, chassis: 'black', bumper: 'black' },
{ car: 'Nissan', year: 2018, chassis: 'blue', bumper: 'blue' },
{ car: 'Chrysler', year: 2019, chassis: 'yellow', bumper: 'black' },
{ car: 'Volvo', year: 2020, chassis: 'white', bumper: 'gray' },
];
readonly gridSettings: GridSettings = {
height: 'auto',
colHeaders: ['Car', 'Year', 'Chassis color', 'Bumper color'],
autoWrapRow: true,
autoWrapCol: true
};
ngAfterViewInit(): void {
const hot = this.hotTable?.hotInstance;
hot?.updateSettings({
cells: (row, _col, prop) => {
if (hot.getDataAtRowProp(row, prop as string) === 'Nissan') {
return { editor: false };
}
return { editor: 'text' };
},
});
}
}
